In what units is gas pressure typically measured?

Gas pressure is commonly measured in inches of water column (in WC) in the context of gas appliances and commercial food equipment. This measurement reflects the pressure exerted by a column of water that is a specific height, serving as an effective unit for low-pressure gas systems typically used in restaurant and commercial kitchen equipment.

Inches of water column is particularly useful for measuring the pressure of natural gas and propane used in cooking equipment, as it allows technicians to assess the gas supply and ensure that appliances are functioning at the appropriate pressure levels. It's a practical unit in the field because it aligns well with the operational pressures experienced in these systems, making it highly relevant for service and repair work.

While Pascals, pounds per square inch, and atmospheres are also valid units of pressure, they are not as widely used in the specific context of gas appliances within the commercial food service industry. Pascals are a metric unit commonly used in various scientific and engineering applications, pounds per square inch is a standard measurement in some types of industrial and pneumatic applications, and atmospheres are often associated with environments under high-pressure situations rather than typical gas appliance operation.
